SCRUBBING DEVICE.

To all whom it may concern:

Be it known that I, HARRY C. PITTINGER, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Scrubbing Devices, of which the following is a specification.

This invention relates to improvements in scrubbing devices for cleaning purposes, the object of the invention being to provide means for readily wringing 'a scrubbing element, forming part of "my invention, without the necessity of touching the said element during the wringing operation.

Another object of this invention is to provide novel means for retaining the scrub bing element in a fixed positionwhile it is being used, so that a proposed scrubbing action can be readily accomplished.

A further object of this invention is to provide a device of the character described, which is simple in construction, positive in action, inexpensive in manufacture, and highly efiicient in use.

Other objects and advantages will be apparent during the course of the following description In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of the device,

Figure 2 is a perspective view of a spring element, forming a part of my invention,

Figure 3 is a vertical section through the handle of the device, taken on the line 33 of Figure 4,

Figure 4is a transverse section through the handle of the device, taken on the line 44 of Figure 3,

Figure 5 is a sectional detail of means for supporting the scrubbing element, the said element being here illustrated as being in a position prior to its use as a scrubbing element,

Figure 6 is a fragmentary detail of the scrubbing element in position for use, with its supporting means being shown in section, and

Figure 7 is an end elevation of a protecting cap, forming part of my invention.

In the accompanying drawings wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the

apparent that the extremity of the handle is of a smaller diameter than its main body portion.

' P t o e ith n h ex r mity l3 a d adapted t m e fr ely er i s a colla 14 provided with a notch 16, which receives therein the raised portion 17 of a spring element 18. The body portion of the spring is adapted to conform to the contour of the collar and terminates in an angular 'arm 19,

which is securely retained in a fixed position.

between the inner periphery of the cap 12 and the other periphery of the collar 14.

As shown to advantage in Figures 3-and 4, the purpose of thespring element 18 will be readily apparent, namely of checking" the rotary movement of the eoll'ar asit is rotated by the turning of a crank arm 20 of an elongated rod 21. This rod penetrates the bore 11 of the handle and terminates at one end in a hook portion 22 adapted to receive therein one extremity of an endless scrubbing element or mop 28, preferably made of cloth or other suitable material. The rod 21 above referred to, is preferably made of a single strand of wire, bent at one extremity to form the hook portion 22 and shaped at the other extremity to provide the crank arm 20.

Positioned on the rod 21 for a longitudinal sliding movement between the hook portion 22 and the cap 12, is a movable arm 24. This arm terminates at one end in a hook portion 25 and adjacent the other end in a coiled extremity 26. It will likewise be observed that this arm can'be made of a single strand of wire with the hook portion 25 formed on one end and the coiled extremity 26 on the opposite end, the said extremity having formed therein a recess 27. This recess serves to receive therein a lug 28, integrally formed with the cap and extending into the aperture formed therein, when the coiled extremity of the arm 24 is moved rearwardly to contact with and be received within the cap 12.

When this adjustment of the arm 24 has been accomplished, the operator of the device by turning the crank arm will cause the scrubbing element now extended to its full length to be wrapped about the rod 21 and accordingly wrung. By virtue of the lug 28 remaining in the recess, the arm 24 will be the rod, while the hook arm, due to the movement of the crank arm, will turn with the rod and thus accomplish the above men-' tioned operation of wringing the scrubbing element.

When the device is first used as a cleaning device prior to the wringing of the scrubbing element, the latter element assumes the position shown to advantage in Figure 6. lVhen the lower hook portion 25 is disposed beneaththe upper hookportion 22, the operator grasps the device by its handle 10 and accomplishes a cleaning operation by readily scrubbed.

From the foregoing description taken in conjunction with the drawings, it will be apparent that I have devised a washing apparatus that embodies not only means for readily wringing a scrubbing element by a simple manual turning of the crank arm, but a device that also includes supporting means whereby a fresh scrubbing element can be readily applied to the apparatus without in any way altering the construction of the same.

It is to be understood that the form of my invention herewith shown and described, is to be taken as preferredexample of the same,

and that various changes in the shapefsize and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a device of the character described, including a tubular handle, a cap secured on said handle, a rod extending through said handle, a crank formed integral with said rod, a movable arm slidably mounted on said rod, a scrubbing element connected to said rod and said arm, and means carried by said cap'for preventing rotation of said movable V 7 arm with respect to said handle. moving'the device over an object to be 2. In a device of the character described, includlng a tubular handle, a cap secured on said handle, a rod extending tirough said handle, a crank formed integral with said.

rod, a movable arm slidably mounted on said rod, a scrubbing element connected to said rod and said arms, means carried by said cap for preventing rotation of said movable arm withrespect to said handle, a collar mounted on said-rod and Within said cap, a notch formed in said collar, a spring mounted in said cap and adapted to engage said notch j for the purpose of temporarily retaining sald rod agalnst rotation with respectto said handle.

In testimony whereof I ailix my signature.
